Thomas Rudolphe Kanza or Nsenga Kanza (10 October 1933 – 25 October 2004) was a Congolese diplomat. He was one of the first Congolese nationals to graduate from a university. From 1960–1962 he served as the Democratic Republic of the Congo (then Republic of the Congo)'s first ambassador to the United Nations and from 1962–1964 was a delegate to the United Kingdom. His opposition to the governments of Moïse Tshombe and Joseph-Désiré Mobutu led him to first rebel and ultimately flee the Congo. He returned in 1983 and resumed politics. From Mobutu's ousting in 1997 until his own death, Kanza served in diplomatic roles for the Congo.
